TELE SCOPE -MOUN TING.

To all whom it may concern:

Be it known that I, FREDERICK L. SMITH, a citizen of the United States of America, residing at Chicopee Falls, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Telescope-Mountings. of which the following is a specification.

This invention relates to improvements in telescope mountings for rifles, the object of the invention being to provide a device that can be readily attached to, and removed from, the rifle barrel.

Broadly stated, the invention consists in providing the upper side of the barrel with a transversely arranged groove and wedge or dove-tailed shape in cross section, and securing therein a ring having a foot or base-piece of corresponding shape which is made to slidably engage the groove, said ring being provided with suitable means for locking the ring in the groove, the ring being provided with means for adjustably holding the telesccipe.

n the drawings forming part of this application,-Figure 1 is an end elevation showing the end of the barrel in outline and the ring secured thereto for mounting the telescope, and the means for adj ustably holding the telescope in the ring. Fig. 2 is a lon gitudinal sectional elevation on the line 22 Fig. 1 through the barrel and the footpiece of the ring. Fig. 3 is an end elevation showing the ring disposed over the axis of the barrel. Fig. 4 is a longitudinal sectional View on the line 44 of Fig. 3 through the barrel and the base portion of the ring, clearly showing in side elevation the means for locking the ring to the barrel. Fig. 5 is a plan view on the line 5 5, of Fig. 2, and Fig. 6 is a horizontal sectional plan view on the line 6-6 of Fig. 4.

Referring to the drawings in detail, a designates the barrel of the rifle that is provided on the upper side thereof with a trans versely located groove 1), dovetailed in shape in cross section, and extending transversely of the barrel, the ring for holding the telescope being designated by the letter 0. This ring is provided with a base or foot-piece (1 also dovetailed in cross section so as to slidably engage the groove 5,

foot-piece d is provided with an extension 6 in the outer end of which is threaded a short screw f which engages the upper surface of the barrel, as designated at g. This screw serves as a means for leveling or bringing the extension piece 6 parallel with the axis or bore of the rifle and at the same time bringing the ring 0 at right angles to the bore of the rifle. In order to lock the ring to the barrel, a screw it is provided which passes through the extension piece 6 and into a threaded opening in the upper portion of the barrel, whereby when this screw is turned down into the barrel, the foot-piece (Z is securely locked in the dove-tailed groove I), the part (Z bearing on the bottom of the groove Z), the screwf at the same time preventing the screw it from moving the ring 0 out of its vertical position of adjustment.

Referring now to the construction shown in Figs. 4 and 6 of the drawings, in which the ring 0 is provided with oppositely extending projections i and j,the projection i being provided with a screw it and the projection with two screws m and a. By rotating these three screws downward against the upper surface of the barrel, the dove-tailed footpiece 0 will be forced upward against the inclined side walls p of the groove 5. These three screws also permit the ring 0 to be accurately positioned in the vertical plane and they also permit the ring 0 to be slightly tipped, transversely if necessary, either to the right or to the left of a vertical plane passing through the axis of the barrel. In

order to adjustably secure the telescope q in the ring 0, the ordinary screws 8 and t, are employed which will hold the telescope g against a spring-plunger 1), whereby the telescope may be moved in the ring 0 for the pur pose of adjusting the same. Fig. 1 shows the ring 0 offset from the vertical plane of the barrel.
